## Plus d'informations sur les réponses OpenAPI

Pour voir exactement ce que vous pouvez inclure dans les réponses, vous pouvez consulter ces sections dans la spécification OpenAPI :

E assim deve ser porque seria um bug no seu código ter o `ValidationError` do Pydantic na sua *response*, ou em qualquer outro lugar do seu código (que não na requisição do cliente).

E enquanto você conserta o bug, os clientes / usuários não deveriam ter acesso às informações internas do erro, porque, desse modo, haveria exposição de uma vulnerabilidade de segurança.

Do mesmo modo, você pode sobreescrever o `HTTPException`.

In this example, the program is asking for Go 1.21 semantics and
then asking for the old pre-Go 1.21 `panic(nil)` behavior and the
new Go 1.23 `asynctimerchan=0` behavior.

Only the work module's `go.mod` is consulted for `godebug` directives.
Any directives in required dependency modules are ignored.
It is an error to list a `godebug` with an unrecognized setting.
(Toolchains older than Go 1.23 reject all `godebug` lines, since they do not

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
